GEORGE D. HECK, OF PRINCE BAY, NEIN YORK, ASSIGNOR TO THE S. S. WHITEDENTAL MANUFACTURING COMPANY, A CORPORATION OF PENNSYLVANIA.

SPITTOON.

Application filed August 9, 1918.

T all whom z'r may concern.'

Be it known that I, GEORGE D. HECK, a citizen of the United States, anda resident of Prince Bay, in the county of Richmond,

State of New York, have invented certain new and useful Improvements inSpittoons, of which the following is a specification, reference beinghad to the accompanying drawings.

My invention relates particularly to fountain or flush spittoons, and isespecially directed to spittoons having an attachment for a salivaejector, and adapted for use of dentists, physicians, surgeons, etc.

The principal objects of my invention are, to provide a spit-toon with asaliva ejector arranged to be discharged directly into the waste-pipeconnections and to provide means to noiselessly release and dischargeany air that may be trapped in the waste connections, and to direct themoisture-laden air thus released into the spittoon bowl.

Other objects of my invention are, to provide means to automaticallyseal the passageway between the waste-pipe connections and the salivaejector when the latter is: not in use, and arranged to be opened by theflow oit' water which actuates said saliva ejector.

My invention comprehends a novel arrangement of the valves and passagesconnecting the valve-head with the waste connections, andalso includesmeans adjustable to limit the opening movement of said valves. c

Specilically stated, the form of my `invention as hereinafter described,comprises a passage-way leading from thesaliva ejector into thewaste-pipe connections. and including a check-valve therein arranged toautouse, and to close when said use is terminated; a vent for the escapeof trapped air in said waste-pipe connection; a delector for divertandalso comprises a spring pressed lever adapted to engage a suitable notchin the valve handle to limit the rotation of the valve in its openingmovement, and arranged to permit the free rotation of said valve in itsclosing' movement.;

matically open when the saliva ejector is iny ing splashed water awayfrom said ventg.

Serial No. 249,041.

My invention also includes all of the various novel features ofconstruction and arrangement as hereinafter more definitely specilied. l

In the accompanying drawings, Figure l is a sectional elevationy of the.spittoon with its mountingand attachments; Fig. 2 is a fragmentarysectional view of said spittoon and its attachments on a Alarger scale;Fig. 3 is a front elevational view of the supply valve-head shown on astill larger scale; and Figa is a sectional elevational view taken onthe line l-et in Fig. 3, showing fragments of the bowl arm and bowl.

In said figures the bowl bracket l is carried in the usual manner by thecrane standard 2, and at its free end supports the bowl arm 3 extendingoppositely from its waste outlet 5, which extends through the downwardlydepended threaded nipple 6 rotatably mounted in a suitable bearing 7 inthe free end. of said bracket l.

The oppositely disposed extensions of the bowl arm 3 comprise inlets 9and l0 from the bowl ll and tumbler-holder l2, respectively. Said bowl1l is conveniently connected with the inlet 9 of the bowl arm by thecollar 13, which carries the reticulated strainer trap 14, having thetunnel l5, and which is provided with the threaded eXtension 16depending into the inlet 9, in threaded engagement with the bowl arm 3.The other extension comprising the inlet l0, of the bowl arm 3, projectslaterally and upwardly beyond the periphery of the bowl, terminating inthe pocket 17 local to the inlet 10, which pocket affords a water sealfor the tumbler-holder l2. l

Said tumbler-holder l2 is provided with a collar 20 in threadedengagement with the hollow standard 2l, which is detachably connected bytheset-screw 22 with the inlet 10 and which has a tubular extension 23depending into the water 2a in the pocket 17 to form a trap forpreventing undesirable sounds and gases from the waste-pipe connectionescaping through said tumblerholder.

Thebowl yarm 3 carries the valve-head 25 comprising the valve 26 havingthe handle 27 for controlling the water supply to the tumbler 29 (shownin dot and dash lines in Fig. 2), in the tumbler-holder 12; the valve 30having the operating handle 31 for controlling the water supply to thespittoon bowl 11, and the valve 32 having the operating handle 33 forcontrolling the water supply in connection with the saliva ejector tobehereinafter described.

The valve-head is connected with the nipples 35, 36 and 37, on the bowlarm 3, the unions 38, 39 and 40, respectively comprising the union nuts41, 42 and 43, through which the various passage-ways leading from thewater distributing chamber 45 in the valve-head 25 and controlled by thevalves 26, and 32, respectively, extend, the water being supplied tosaid water distributing chamber by the water supply pipe or tube 44.

The valve 26 has the plunger 46, cooperatively related with the valveseat 47, and controls the passage-way from the water chamber 45 in thevalve-head 25, to the tumbler 29, comprising the union 3S, tubularconduit 4S, leading upwardly through the hollow standard 21 andconnected through the side of said standard with the goose-neck 49 fordirecting water into the tumbler 29, from which the overflow iows intothe dished tumbler-holder 12, lthrough the hollow standard 21 and intothe wastepipe connections through the inlet 10 and arm 3.

The valve 3() is provided with a plunger 50 cooperatively related withthe valve-seat 51, and controls the passage-way leading from the chamber45 in the valve-head 25, to the spittoon bowl 11, comprising` the duct52,' union 39, nipple 36, duct 53, plug 54, union 55, goose-neck 56, andnozzle 57 discharging into the bowl l1.

The valve 32 for controlling the saliva ejector (not shown), is providedwith the plunger 59 cooperatively related with the valve-seat 60, andcontrols the passage-way leading from the chamber 45 in the valvehead25, into the bowl arm 3, through the duct 61, nozzle 62 ot' the injector63, duct 64, union 40, and port 65, into the bowl arm 3. Said injector63 is removably connected in screw-threaded relation with the valve-head25, and comprises the slotted head 66 by which it may be rotated by ascrew-driver, into or out of its operative position or removed therefromit desired.

The saliva ejector, (notA shown) is connected by the flexible tubing69,through the union 70 comprising the union nut 71.` and duct 72 in thenipple 73 and valve-head 25. with the duct 64 into which said duct 72leads, adjacent to the outlet end of the nozzle '62 of the injector 63,so that when the valve 32 is opened, water from the valvej head 25 isdirected through the injector and.

into the bowl arm 3, thereby forming a suction in the saliva ejectortube to draw saliva therethrough and discharge it directly into saidbowl arm 3 and the waste-pipe connections attached thereto.

Thc passage-way leading through the union 40 `is conveniently providedwith a check valve 75 having the guiding stem 7 6 extending through saidunion, and having the conical intermediate surface cooperative with theend of said union as a valve-seat to automatically close saidpassage-way when the valve is closed and the saliva ejector is not inoperation, to prevent undesirable gases from the waste-pipe connectionsentering the saliva ejector tube and parts connected therewith. As shownin fltig. 4,the check valve 75 is limited in its upward movement by thepin 77 extending transversely across the passage-way in the nipple 36.

rl"he`valve 32 also controls the duct 79 leading to the nipple 60 andunion 81 to which the tlcXible tube 82 is connected ior directing waterto a syringe or other suitable device, (not shown), which may beattached to the t'ree end of said tube 82.

it will be obvious that the saliva ejector tube will carry considerableaerated fluid into the bowl arm and waste-pipe connections, andtherefore, said bowl arm is provided with tbe vent outlet passage-waywhich is restricted by the plug 54, whose one side is cut away, as shownat 35 in 4. to provide a restricted vent tor the tree escape oit' anyair that may be trapped in said bowl arm. Said vent outlet passage-way83 is connected by the tubular extension 66 which has its outlet orilicedirected into the spittoon bowl 11, and preferably conforms to thegoose-neck 56 by which it is conveniently carried.

lt has been found in practice that there is a tendency, especially withthe juvenile patients, to maliciously turn on the valve leading to thetumbler and thereby unduly overflow the saine, and to prevent suchaction, the valve 26 is provided with a spring pressed lever 89 arrangedto be maintained by the spring 90, either in its inoperative positionshown in dotted lines, or in its operative position as shown in fulllines, and arranged to engage the shoulder 91 on the rotary valve-handle27 in the anti-clockwise or openingmovement of the valve-handle 27, tolimit the flow ot' water from the chainber 45 through said valve intothe passageway leading to the tumbler. Said valvehandle 27 is providedwith the edge 93 disposed opposite to said shoulder 91, and arranged toride under the lever 89, affording a free movement of the valve-handle27 in a clockwise or closing movement to close they valve 26.

As it isdesirable that the iow of water into the tumbler may be varied,the valvelilo head 27 is arranged to be rotatably set with respect toits plug 46 by the set screw 94 as best shown in F ig. 2.

The valve-head 25 is conveniently provided with the outer cover plate 95which is removably attached to the bowl arm S'by the screws 96, andwhich conveniently carries the lever 89 and its spring 90.

The plug 54 shown in Figs. l, 2 and 4, is of a diameter substantiallyequal to the transverse dimension ot the bowl arm, local to said plug,and said plug is provided with a depending apron or extension 97 servingas a deiiector, arranged to divert any waste or splashed water coming'from the tumblerholder or saliva ejector that might be so splashed asto enter the vent outlet 88, and sputter torth from the dischargeorifice oi" said outlet.

llthe tumbler-holder l2 is bowl-shaped, havingtheA internal radiallydisposed ribs 98, which have their central portions offset to provideshoulders 99 between which the tumbler 29 may rest upon the offsetportions of said ribs.

.Vater is admitted through the supply tube 44 into the chamber 45 in thevalve-head 25, and the flow of water in thev spittoon bowl ll iscontrolled by the valve 30, whose plunger 59 is arranged to be engagedwith or be retracted from its valve seat 5i by rotation of the handle3l, to control the flow of water to said bowl l1, through vthepassage-way comprising the bore 52, union 39, bore 53, union 55,goose-neck 56 and nozzle 57. The How ot water to the tumbler isconveniently controlled by the valve 26 Whose plunger 46 may be engagedwith and retracted from its seat 49 by rotation of the valve-handle 27,to control the flow of water from the chamber through the passage-waycomprising the union 8S, nipple 35, tubular conduit 48,

and goose-neck 49 into the tumbler, the overflow otl which is caught bythe tumblerholder l2 and carried b v the hollow tubular standard 2lthrough the trap 17 into the inlet 10 and the bowl arm 3 and awaythrough the waste-pipe connections.

The flow et' water for actuating the saliva ejector is controlled by thevalve 32 whose plunger 59 may be engaged with and retracted from itsseat 60, by rotation of the valve-handle to control the tlow ot waterfrom the chamber through the duct 6l nozzle 62, duct 64, union 38, andoutlet aperture 65, into the bowl arm 3, and as will be obvious, thetorce ot the water from the nozzle will form such suction in the duct 72and iiexible tubing 69 as to draw saliva therethrough trom the salivaejector into the bowl arm 3 'trom where it is discharged through thewastepipe. When said valve 32 vis open, water leading to a syringe orother suitable device is admitted through the duct 79 and eaible tube 82under pressure.

l do not desire to limit my invention to the precise details oilconstruction and a1'- langement as. herein set `forth, as it is obviousthat various modifications may be made therein without departing fromthe essential features of my invention as delined in the appendedclaims.
